Project description

backupmystemusb2usb is a Creative Commons Python package to copy usb key.

Its runs on Python 3.7 and has a dependency for yaml, and another one for the gui.

Installation without the source

To install backupmysytemusb2usb package run the following command:

sudo apt-get install libyaml-dev python3-gi
sudo -H pip3 install backupmystemusb2usb

You have to create a config.yml file (you can save it into your ~/.local/share/backupmysystemusb2usb directory)

UUID_1_Master: 790d1fbb-96ed-46c3-868d-08e05e223fa7
UUID_1_Slave: 790d1fbb-96ed-46c3-868d-08e05e223fa7
Temp_img: /home/stephane/Temp/Linux.img
Temp_log: /home/stephane/Temp/BackupMySystem-Temp.log
Kill_dd: True

UUID list

sudo blkid

Find your device and to change the label if the device master UUID is the same as the slave UUID (for exemple: if you cancel in copying temporary img to disk slave), you have to put a date upper on master than slave

Warning UUID is not Label !

sudo e2label /dev/sd_1 "19991231235959"

For the deamon, write a for running by user root with chmod 700

#!/usr/bin/env python3
import sys
import yaml
from backupmysystemusb2usb.usb2usb import usb2usb
   u2u = usb2usb(sys.argv[1])
except yaml.YAMLError:

You can create a service systemd if you planed to backup your usb key every day in the morning. You can wakeonlan from a raspberrypi or with another technic

wakeonlan MACADRESS
crontab -e
# write your cron
sudo service cron reload

Now to create a daemon in startup (without console).

Use this name “backupmysystemusb2usb” because in source this file is a constant for GUI progress for non-root user

cd /etc/systemd/system
vi backupmysystemusb2usb.service



ExecStart=/usr/bin/sh -c "/your/working/path/ /your/working/path/config.yml"


Enable and start

sudo systemctl daemon-reload
sudo systemctl enable backupmysystemusb2usb

Then the service start on reboot. If you will test now the service :

sudo systemctl start backupmysystemusb2usb

Check the log (the last 20 messages)

sudo journalctl --unit backupmysystemusb2usb -n 20

You can go to check your output log file configured by config.yml

Now we have to create the shell return for non-root user

chmod 700

And write in file

#!/usr/bin/env python3
import yaml
from backupmysystemusb2usb.usb2usb import usb2usb
u2u = usb2usb('/path/to/your/config.yml')

You can create a autostart Gnome desktop startup

cd ~/.config/autostart
touch backupmysystemusb2usb.desktop
chmod 744
vi backupmysystemusb2usb.desktop

And in your editor enter
